Title: Heavy vehicle rear axle mountings - cold forged and water quenched
IPC: B21D53/90
Filed: 1970-06-18

Title: Distilling liquids esp dirty solvents - using horizontal flow along directly heated surface
Inventor: BRAUN BERND
IPC: B01D3/00

Abstract: A vessel into which the liquids are introduced is near one end above the feed end of a horizontal evaporator surface heated by a heater device. The surface is part of an endless belt, with the heaters beneath its upper length and the liquid fed to one end of this length, so that it evaporates as the belt conveys it along. In the addition, the evaporator surface constitutes of the upper surface of a radiator through which a heating fluid flows; the liquid is conveyed along this horizontal fixed surface by a moving wiper device above the surface, esp. a reciprocating device which sweeps in one direction and in inactive on the return stroke. More efficient heating is obtained due to direct contact between heater and evaporating surface and the facility for insulating the underside of the heater.
